Out of process way

Hi
I am working on a project where in the idea is the Applet servlet interaction
From my remote client Applet i am accessing the servlet on the webserver. My idea is to fire an out of process Executable using the Runtime Class in the servlet. This executable shuld execute the moment i am trigerring from my client applet via the servlet. Now when i am doing so i am getting the handle of the process i start by firing the exe. Now my problem is that i should also be able to destroy the process from the applet via the servlet. Is it possible?
Will i get back the same process handle back some how using which i can destroy the process or will i lose the process handle the moment i lose the connection between the applet and servlet which happens the moment my control returns back to the applet after starting the process.
